W TER-HEATER.

Application filed July 25, 1919.

. To all whom it may concern:

Be it known that I, LOUIS F. FAUST, a citizen of the United States, residing at Comfort, in the county of Kendall and State of Texas, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification.

This invention relates to new and useful improvements in water heaters.

The object of the invention is to provide a simple, efficient and economical water heater which will heat a quantity of water in a short time and in a safe and convenient manner. r

In carrying out the invention a water reservoir or tank is suspended within a) jacketed casing and provided with upright converging draft tubes. The tank is spaced from the casing, so that the heat from the fire box must pass around the tank as well as through the tubes. The converging tubes tend'to increase the velocity of the gases at their upper ends, but also produce a retarding effect which intensifies the heat.

One of the features is the arrangement whereby the cool water is delivered through the body of water to the bottom of the tank thereby displacing the hot water at the top. The tank is thus always filled with water and an open discharge pipe for the hot water prevents the generation of steam and makes for safety. uch a structure aflfords a large heating surface, a strong draft and thereby quick heating.

The invention will be-more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fi ure 1 is an elevation of a heater embodying the invention,

4 Fig. 2 is a vertical sectional view of the same, and

Fig. 3 is a cross-sectional view on the 11m 33 of Fig. 2.

In the drawings the numeral 1 designates a dished cast metal bottom having an ornamental base fiange 2. A casing comprising an outer sheet metal shell 3 and an inner sheet metal shell 4 rests on the base, snugly within the flange. The casing is cylindrical and the two shells are fastened together at their upper and lower ends, whereby a jacket is provided and a dead air space had.

he dead air space acts as an insulator so Specification of Letters Patent.

thitgsl the casing will retain heat and exclude co Brackets 5 are fastened in the casing and support a cylindrical water-tank 6, preferably formed of thin sheet metal The tank is smaller than the inner shell 4 so as to provide an annular vertical space therebetween. A plurality of tubes or' fiues 7 extend vertically entirely through the tank. Each tube converges toward its upper end thereby tending to increase the velocity of the gases at its upper end, but also producing a retarding effect which intensifies the heat. The bottom of the tank may be-concaved which would tend to concentrate the fire inthe fire box under the tank and offer also, a reater heating surface. The tubes being 0 thin metal and spacedproperly in the tank will radiate the heat and thoroughly heat the water in the tank. A portion of the heat passing up the space between the casing and the tank will heat the cylindrical wall of the tank, so that. the water will be expeditiously heated.

An ornamental ring 8 rests on top of the casing and a cover 9 is fastened on the ring and to the casing, said cover having a central, flanged flue hole 10 for receiving an ordinary stove pipe 11 in which a damper .12 may be placed. A water supply pipe 13 hot water pipe has an extension 18 directed laterally and curved downward so as to discharge a stream into a suitable receptacle as a bucket or bath tub, etc. It will be noted that both the cut-off valve 15 and the end of the extension 18 are well above the top of the water tank 6 and consequently the said tank is always full of water. The extension 18 being'at all times open, steam cannot collect in the tank nor can any dangerous pressure accumulate. The device is thus absolutely safe, although heating water very rapidly.

A door 19 covers the opening to the fire box and this door is provided with a screw damper 20 whereby the draft may be regulated. The bottom 1 is supported on suitable legs 21. It will be seen that the entire structure is simple and compact. By disconnecting the pipe 13 and unfastening the cover 9, the tank -6 may be easily lifted from the casing when desired.

In using the heater a fire is made in the fire box under the tank, the cast bottom 1 permitting a very hot fire. Wood or other fuel may be used. The heat passing up through the converging or contracted tubes 7 will be fully utilized and a sufiicient draft will be had to create a hot blast. As the heat passes through the tubes and around the sides of the tank, the water therein will be quickly heated owing to the radiation and conduction had by reason of the disposition of the tubes and the thin metal used. When the water in the tank is heated it may be discharged by way of the pipe 16 and extension 18, by opening the valve 15, whereby cool water is admitted at the bottom of the tank, thereby displacing the hot water which passes out through the pipe 16.

What I claim, is:

In a water heater, a bottom being provided at its periphery witlfa base flange, an

outer shell having its lower end fitting within the base flange and resting upon said bottom, an inner shell disposed in spaced concentric relation within the outer shell for forming therewith a dead air space, said inner shell having its upper and'lpwer ends bent outwardly to engage the inner surface of the outer shell, the lower end of the inner shell contacting with the outer shell adjacent its engagement with the base flange and thereby serving to reinforce and stiffen the same, legs supporting the base flange and secured thereto, a cover secured to the upper end of the outer shell, a water tank arranged in spaced concentric relationwithin the inner shell and having longitudinal flues, elements secured to the inner shell and supporting the lower end of the water tank, and inlet and outlet pipes for the water tank serving to connect the cover and water tank and retaining the proper concentric position of the tank with relation to the inner shell.

In testimony whereof I afiix my signature.

LOUIS F. FAUST.
